UCMSC(Umbilical cord derived Mesenchymal cells) demonstrate very low immunogenicity, good homing and tumoricidal properties. These help to attenuate the tumor growth in cancer treatment. The possible mechanisms are secretion of proteins which induce apoptosis of cancer cells and also arrest cell cycle and the other is enhancement of immune reaction between UCMSC, cancer cells and dead cells. Also due to its good homing capacity to tumor tissue UCMSC can be used as a vehicle for targeted cancer therapy.

Embryonic stem cells are in discussion for their pluripotency and applications. Also they are equally in discussion due to their source and ethical, legal and religious issue related with that. Lori P.Knowles has very fascinatingly compiled view of different religion about Embryonic stem cells research. Although Autologus adult stem cells and cord blood stem cells are not part of this discussion and this could be one of the reason scientist are focusing on iPS (Induce pluripotent stem cells), which has similar properties as embryonic stem cells with source material as adult stem cells.

When patient has poor quality of eggs (oocytes) there will be a possible option of oocyte donation but this new technique which gives strontium treatment to oocytes can make it possible to fertilize such eggs and make a successful embryo!!!

It is known that receptors on the cell surface have the capability of selectively binding or adhering to other "signaling" molecules. These proteins can be thought of as a conduit for the transfer of information from the outside of the cell to the inside of the cell. Cell-surface receptors can be generalized into three distinct categories based on the mechanism they use to accomplish transmission of information into interior of the cells. Several human diseases have been linked to alterations in cell-surface receptors as they activate intracellular signaling cascades, which regulate numerous cellular functions from cell division to cell growth and development.
